With the disappointing sales of the C-series, I see PW has a lot of interest to get their engines to the market, so they will take a share of the costs - then I see how the Airbus part of the costs can be as low...

Quoting mat66 (Reply 5):Will there only be one engine as an option ? I thought it will be both.

Waiting to stand corrected...

As am I...

I thought that in the interest of cost and time to market there would only be one engine certified.

This article uses "and" instead of "or" in the engine choices, so it very well may be that two will be certified.

The section of interest:

New engines would involve a more fuel-efficient version of the CFM56 model with a new hot section, or core, and a new model from Pratt & Whitney, whose geared turbofan allows the outer fan to turn at different speeds, using less fuel.

Quoting Kappel (Reply 14):First indeed the sharklets. The wings need to be strengthened to cope with the larger engines. I believe there will also be some aerodynamic upgrades here and there.

The sharklets predate the NEO program, so I'm sure you can get them even if Airbus decides not to go with the NEO.

And it seems both vendors roll out incremental aerodynamic upgrades as they are available.

The article gives us an interesting list of what stuff is being done for NEO specifically:

Airbus has forged preliminary agreements with two engine makers and is talking to suppliers of nacelles that house the engines, landing gear, and other equipment that would need changing, he said.

Not very thorough, but it is interesting to see they have already got preliminary agreements with Pratt and CFM.

It will be interesting to see if either Pratt or CFM will be risk-sharing partners.

In the case of Pratt, they really do need the business, but wonder how far the BoD will let them go in terms of buying their way onto what is known to be an interim aircraft.

But in reading the CFM Wiki page, it really takes a long time to get a new engine established, and if Pratt is serious about the GTF, this may be a great chance for them to get their nose into the tent.

Quoting columba (Reply 15):The A318 has no chance against the EJet or the CSeries it is too heavy even new engines won´t help that. The first A318s are already being scrapped as they have no market.

It might an option as "long range" jet, like BA is using it from London City. But the costs of getting the engine on that airframe, and considering the market of only a few airframes. So, I think you are right.

From a structural standpoint, passengers are the worst possible payload. [Michael Chun-Yung Niu]
